Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack an efficient method to detect and respond to objects contacting the device, limiting their ability to perform specific operations based on object recognition, which hinders user interaction and functionality enhancement.

Incorporating a proximity sensor unit to detect objects and a control unit to determine and perform corresponding operations, allowing the terminal to recognize shapes and locations, enabling intuitive user input and menu navigation through figure input recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input methods are used for menu navigation, then the terminal can perform basic operations, but user interaction efficiency and intuitiveness are limited
Solution Approach 1:
The patent replaces traditional mechanical input methods (physical buttons, keyboards) with an optical detection system. The proximity sensor detects the shape and location of objects placed near the terminal, and the control unit processes this information to perform corresponding operations, substituting mechanical input with optical-field-based recognition.
Solution Approach 2:
The terminal automatically detects and processes user input through the proximity sensor and control unit without requiring manual button presses or typing. The system self-services by recognizing the shape and location of placed objects and autonomously executing the corresponding menu operations, reducing the need for complex user interactions.
2Adaptability or versatility
If no object detection capability is provided, then the terminal structure remains simple, but the terminal cannot recognize shapes and perform object-based operations
Solution Approach 1:
The proximity sensor and control unit serve multiple functions: detecting the presence of objects, recognizing their shapes, determining their locations, and triggering corresponding operations. This multi-functional approach adds object recognition capability without requiring separate dedicated components for each function, thereby limiting the increase in device complexity.
3Ease of operation
If shape and location-based menu navigation is implemented, then menu access becomes more intuitive, but the system complexity increases
Solution Approach 1:
The control unit acts as an intermediary between the proximity sensor and the menu system. It receives detection data from the sensor, processes the shape and location information, and translates it into corresponding menu operations. This intermediary layer simplifies the overall system architecture by centralizing the processing logic and avoiding direct complex interactions between multiple components.
